Since commitcf176128ec("boot/arm-trusted-firmware: add SSP option"), we are passing ENABLE_STACK_PROTECTOR=none when we want to disable SSP usage in TF-A. While this works fine in recent versions of TF-A, older versions such as TF-A will end up passing -fstack-protector-none in this situation, which fails as this is not a valid gcc option (the valid gcc option is -fno-stack-protector). To solve this, we pass ENABLE_STACK_PROTECTOR=0 which was in older TF-A versions used to say "don't do anything with SSP", and is also still supported in newer versions of TF-A.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
